Here's my 5903 with Adj Sights, square trigger guard, and laser devices inc BA-2. Its fitting to take a pic on the S&W bible the current 4th edition. The laser mates perfectly with my 5903 as the laser is dated 1991, and my 5903 was made May of 1990. The adjustments on the laser are kinda wonky but I think i have it figured out in order to make it half way work.
